Pplleeaassee hheellppa rain gauge collected 2 1/3 inches of rain in october, 5 1/2 inches in november, and 3 3/8 inches in december. find the total rainfall for those three months.

We simply need to find a common denominator. The common denominator between the two (LCM/Least common multiple for denominator) is 24.

Now, we multiply the numerators also. We have our new numbers: 2 8/24 for October, 12/24 for November, and 3 9/24 for December. Now, we have to add them together. 2 8/24 + 12/24 = 2 20/24

Now, add the December value to the combined October/November values.

2 20/24 + 3 9/24 = 5 29/24

Now, we need to simplify the fraction.

6 9/24
